' UNITED STATES VALENTIN \VEBER AND JAMES R. HARRISON, OF PRINOEVILLE, ILLINOIS,

PATENT OFFICE-o ASSIGNOR OF ONE-THIRD TO IVILLIAM HARRISON, OF SAME PLACE.

AUTOMATIC WElG HlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 326,074, dated September 8, 1885.

Application filed March 14, 1885.

T 0 aZZ whom it may concern:

Be it known that we, VALENTIN WEBER and J AMEs B. HARRIsoN, both residents of Princeville, in the State of Illinois, have invented a new and useful Improvement in Automatic WVeighing Machines, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a perspective elevation of my improved automatic weighingmachine, and Fig. 2 is a front view, partly in section; Fig. 3, detail face view of Fig. 2, showing dial-face and hand; Fig. 4, detail of wheels and pawls, 800., of Fig. 1.

The object of our invention is to provide an automatic weighing-machine capable of being attached to threshing machines, so as to receive the grain therefrom and measure and Weigh the same automatically, all of which will now be set forth in detail.

In the accompanying drawings, A repre sents the machine mounted on asuitable frame, and A guide pulleys by which the weighinghopper is held in a vertical position.

B (indicated by dotted lines) is the spout from the elevator to carry the grain to the machine, and the elevator may be of any suitable pattern or form best adapted for the purpose.

B is a shaft located at one side of the machine-frame, which contains on its outer end asprocket-wheel, G, by which it is driven, and on its inner end a pinion, G. Centrally it has a pulley, D, with a ratchet-wheel, D, on one side.

E is a trippawl or starter, pivoted to pulley D, that connects with ratchet-wheel D when the machine is thrown in gear by spring E, bearing by friction on pawl or cam-wheel.

F represents an arm projecting from the pawl E, and G is an arm secured to the compound scale-beam M L L of the pivoted weighing-bucket. This arm G intercepts the pawlarm F as it rotates with the wheel D, and when it strikes said arm G the pawl E is released from the ratchet-wheel D, and the sprocket- Wheel 0, with which the ratchet-wheel D is attached, is permitted to turn without turning the shaft B. In practice the sprocket-wheel G is to be moved up against the ratchet-wheel D; but, for illustrating, in Fig. 1, the ratchetwheel and pawl, we have shown the sprocket- (No model.)

wheel at some distance from the ratchet-wheel, and indicated the tube on the shaft B, partly in section. The sprocket-wheel, which receives rotation from a similar wheel on a thrash- 5 5 ing machine, is keyed on the same tubular shaft on which the ratchet-wheel is keyed.

H is a horizontal shaft, journaled crosswise near the base of the two posts directly below and on a line with the shaft B. Each end of this shaft is provided with a crank, H, and the front end of the shaft has a cogwheel, I, which meshes with the pinion O on shaft B. By the side of the cog-wheel I is a projecting arm, I, for the shaft H, which arm is designedto strike at each rotation the ratchetwheel J, which connects with a suitable train of indicating mechanism in the box J, the face-plate of which is not shown in the accompanying drawings.

K is a semi-cylindrical hopper, open on its upper side, and having a central radial partition, K. This hopper has eyes K and connecting-rods L, the upper ends of which are attached to the inner ends of the levers L. 7 These arms are pivoted to the top of the frame at one side and project beyond the frame, where they are united by a rightangled bar, 5 M. These levers have an arm, M, notched on top, which projects beyond this bar, M, and extending downwardly from this arm is a rod, m, which contains an interposing spring,

N, so that the rod may be moved to or from the pivotal point; or instead of the spring a weight may be employed, the object being to 8 3 put sufficient weight on the arm M to counterweight the hopper K and the amount of grain it is desired to weigh before the gates at the base of the hopper are opened.

The bar M, connected with the levers L L, 0 has also a downwardly-projecting right-angled arm, G which comes in contact with the pawlarm F, so that when the hopper descends the arm G becomes disengaged from the pawl-arm.

Centrally across the frame, within and di- 9 3 rectly above the hopper,is a table, 0, pivoted to the frame by means of the arms 0. The hopper on each end, centrally in the are, has a pin, P, to which a lever, P, is pivoted. The upper end of this lever is slotted to re- ICO ceive a pin, Q, which projects out from the table 0. Thelower ends of each of the levers 1? I are hinged to avconneeting-rod, R,which connects with the cranks H on shaft H. The lever Pnear its lower end is pivoted to asliding floor which opens and closes alternately the swing-bottoms S, as shown in Fig. 2.

Having described our improved device, the operation of weighing is briefly as follows: The automatic weighing device is adjusted on the scale-beam M by setting the upper end of the spring-actuated rod toward or from the fulcra'or knife-edges of the levers L L. The grain fiows from a thrashing-machine through the spout B into the hopper K, over the table 0, and into one or the other compartments of the hopper. This hopper, it will be observed, has two sliding doors or curved gate-plates, S, which are actuated by the lever B, acting through the medium of the connectingrod B. These gates are so constructed in their movements that they operate alternately to open and shut the discharge-openings from the vibrating hopper regulated by the movements of the thrasher, so that the vibrating motions of the hopper will be synchronous with the feed motions of the thrashing-machines.

It will be observed that we combine with an auxiliary shaft H a doubleacting striker, l, actuating the indicating mechanism, which shaft accurately follows the movements of the driven shaft B and the vibrating motions of the hopper.

lt will also be observed that the hopper is centrally subdivided and provided with a vibrating distributing-apron, so engaged with all of the partsthat it also vibrates in harmony therewith.

It will be finally observed that we employ,in combination with a vibrating guided hopper,

40 a compound scale-beam,from two of the arms of which the hopper is suspended, and from a single notched scale-beam and a spring-rod adjustable at foot and top the weight of grain or measure is determined. lVe thus have an au- 5 tomatic weighing-receptacle provided with antomatic discharging slides or gates,and means for operating an automatic registering device.

\Vhat we claim as new is 1. The combination of the swinging table 0 and slotted vibrating levers P, pivoted to said table O,with the rods B,crank-shaft H H,and the sliding floor, substantially as described.

2. The combination,with a hopper suspended and divided as described andprovided with discharging-gates, of a table or chute, O, hung as described, a spout, B, leading into the hopper from the grain-discharge of a thrashingmachine, and a discharge-spout below said gates, substantially as described.

3. The combination,in a grain-weighing machine,of a registering apparatus, a suspended vibrating hopper, means, as described, to connect said hopper and said registering device, a sprocket-wheel and a ratchet-wheel, both fixed on the same sl1aft,the lever-pawl pivoted to a cam on the said shaft B, with the compound scale-beam, and the angular arm G,rigidly connected to said compound scale-beam from whichsaid hopper is suspended, subtantially as described.

4c. The combination of a centrally-divided hopper, a vibrating table suspended therein, gates pivoted to the bottom thereof,and an automatic weighing and registering device, and the adjustable tension-rod in, all constructed and adapted to operate substantially as and for the purposes set forth.

5. The combination of a compound scalebeam and avibrating hopper suspended therefrom, guide-rollers A,the angular trip-rod G, a pawl operated thereby, the shaft B, carrying a suitable ratchet-wheel, the register proper, and suitableintermediateconnections between said shaft and the register, substantially as described.

In testimony that we claim the foregoing we have hereunto set our hands, this 21st day of February, 1885, in the presence of witnesses.
